An integration scheme of fuzzy numbers corresponding to static type kn
owledge and dynamic information is presented. The integration scheme,
denoted by compatibility integration scheme (CIS), is content dependen
t and is based on the concept of compatibility between existing knowle
dge and information. It is motivated by the hypothesis that informatio
n serves to support existing knowledge when it is consistent with it,
and to modify and update existing knowledge when the two differ substa
ntially. Several compatibility measures are suggested and analyzed. (C
